the purpose of building the #3 shaft was to facilitate among other things exploration of the HGZ that dips southward towards the Headway.
the attached link is to an old Goldcorp news release and I attach it because I believe it provides some good information on what Goldcorp has suspected about the HGZ and possible similar structures since 2002
the point here in my opinion is that there is justification for further drilling on Headway deep structures.
Thus the reason for Mega completing the acquisition.
all in my feeble and humble opinion.
of course hrattle will tell all that I am a pumping fool who only wants to mislead
